Novel program controlled energy-saving water boiler

Abstract

The invention discloses a novel program controlled energy-saving water boiler. The top of a preheating tank is provided with a water inlet and the lower part of the preheating tank is connected with a water storage tank; a water drop exhaust port is reserved between the water storage tank and the preheating tank; the lower part of the water storage tank is provided with a communicating pipe and the bottom of the water storage tank is communicated with the bottom of a heating tank; the upper part of a gap between the heating tank and the water storage tank is provided with a steam exhaust port; the upper part of the heating tank is provided with a boiled water storage tank and a boiled water boiling outlet is reserved between the heating tank and the boiled water storage tank; the lower end of the boiled water storage tank is provided with a boiled water outlet; and a heating device and a temperature measurement device are arranged in the heating tank. The water boiler has the advantages that: unboiled water enters from the bottom of the heating tank so that unboiled water and boiled water are prevented from mixing; steam in the heating tank is condensed into water through the preheating tank and the water storage tank; the heat of the steam is transferred to cold water to realize cyclic utilization of waste heat so as to save water source and energy source; a water level probe and a digital temperature probe are adopted to finish double anti-dry burning protection, so the reliability of the work of the machine is ensured; and two heating tubes are used for heating, so the heat productivity can be distributed very well to prolong the service life of the heating tubes.

Description

technical field [0001] The invention belongs to the field of commercial electrical equipment, and in particular relates to a novel program-controlled energy-saving water boiler. Background technique [0002] The technical scheme of the water boiler in the prior art is roughly as follows: it includes a water inlet tank and a water inlet. When in use, cold water can directly flow out from the cold water outlet; and when boiling water is needed, just turn on the power and after a period of heating, the boiled water outlet can be opened for use. Like this, brought a lot of convenience to people's life. But it has many defects: 1, if just turn on the power when wanting to use boiling water, it generally needs longer time to be heated to boiling water; It will still be heated repeatedly to form "thousand boiling water", which cannot provide hygienic and safe water for drinkers. 2. Owing to be to enter water from the upper part of heating water tank, raw water enters from the up...

But it has many defects: 1, if just turn on the power when wanting to use boiling water, it generally needs longer time to be heated to boiling water; It will still be heated repeatedly to form "thousand boiling water", which cannot provide hygienic and safe water for drinkers

3. If the user does not pay attention, if there is no water in the heating water tank when the power is normally on, "dry burning" will occur, which will reduce the service life of the heating water tank
